  3. Project Planning

  4. Project Management Process Define Scope & Commit Organization Project Initiation & Start-up Project Planning & Team Formation Project Tracking & Control Project Delivery & Support Develop Plan Execute Plan Track and Control Deliver Product and Close Project

  5. Project Planning and Team Formation • Project Definition • Plan Creation • Project infrastructure • Team formation • Major activities • Key project documents • Project plan sign-off

  6. Project Definition • Problem / Opportunity Statement • Project Mission / Goal • Project Objectives • Success Criteria • Assumptions, Risks, Obstacles

  7. Project Mission Statement • What do we do ? • For whom do we do it ? • How do we go about it ?

  8. Project Objectives • Each Objective should be: • Critical • Observable • Distinguishable • Measurable

  9. Plan Creation

  10. What is the project plan ? A plan is to a project what a route map is to a journey

  11. Project Plan Supporting Departments Customer Project Team Senior Management The Project Plan provides a standard communication tool through out the life cycle of the project

  12. What is the project plan? • The Project Plan documents: • What to do ? • When to do ? • How to do ? • Who is to do ?

  13. Project Infrastructure • Projects need to start with a basic and supporting infrastructure including: • Configuration management: • e.g., a Versioned Object Base (VOB) • Project folder • Project mailing list • Project Web site • Tools acquisition and installation

  14. Team Formation • Members • Initial members • Engineers moved from other projects • Newly hired engineers • Roles assignment • PM,TL,CM,TE,SE,QE, SETE, etc. • Team formation requires... • Adjusting to the working environment • Learning to work with new team members • Sharing and contributing to project objectives • …facilitate and drive the team’s Commitment to project success...

  15. Elements of an Effective Commitment Process • The person making the commitment does so willingly • The commitment is not made lightly; that is, the work involved, the resources, and the schedule are carefully considered • There is an agreement between the parties on what is to be done, by whom, and when • The commitment is openly and publicly stated • The person responsible tries to meet the commitment, even if help is needed • Prior to the commitment date, if it is clear that it cannot be met, advance notice is given and a new commitment negotiated • Watts S. Humphrey

  16. Major Planning Activities • Deploy the project infrastructure and development environment • Ensure appropriate training • General training • Role-based training • Domain-specific training • Produce key planning documents as well as artifacts such as: • Work Breakdown Structure • Estimates • Schedule

  17. Key Project Planning Documents • REQB - Requirement Book • (or Statement Of Work) • SPMP - Project Management Plan • SQAP - Quality Assurance Plan • SCMP - Configuration Management Plan • MBOOK - Metric Book • Project Folder REQB + SPMP forms the virtual “contract” between the Center and the customer...

  18. Key Project Documents: REQB • The document may contain: • Summary of Requirements • System Architecture • System Integration and Testing Strategy • Development Environment Requirements • Target Environment Requirements • Testing Environment Requirements • Training Requirements • Maintenance Policy • Quality Requirements • Technical Risks and Risk Abatement Procedures • Traceability Matrices • List of Deliverables to the Customer

  19. Work Breakdown Structure (WBS) • A hierarchical arrangement of elements of activity from which project estimates can be determined • A tool for planning, managing and reporting on a project • A tool for separating elements of a project for contractual/financial purposes or separating areas of responsibility

  20. Types of Work Breakdown Structure • Product Breakdown • Work Breakdown • Organizational Breakdown • Phase Breakdown

  21. Subsystem X Feature B Feature C Feature D Feature A Component W Component W Component W Component W Component W Component W Component W Component W Component W Product Breakdown • Identifies features or components of the product or service which need to be developed during the project • Based upon the functionality or architecture resulting in units of work for the project

  22. Work Breakdown • Identify activities which need to be performed during the project 6.0 Module A Integration Test 6.1 Qualify submitted modules for integration 6.2 Check-in all code submittals 6.3 Validate build strategy 6.4 Perform parallel builds 6.5 Ramp Test Platform HW 6.6 Ramp Test Platform SW 6.7 Run Tests 6.8 …. 6.n

  23. Organizational Breakdown • Identify Customer Organization & Roles • Identify Other Contractors e.g. Consultants, Vendors, etc. • Identify elements of your own organization participating in the project Subsystem X On-site Customer Team Center Team A Project Planning Contractor B

  24. Phase Breakdown • If a developmental lifecycle model is used, a phase-wise breakdown can be made • Example: • System Requirements • Collect Preliminary Requirements • Analyze Requirements • Document Preliminary SRS • Inspect SRS • Baseline Requirements • Preliminary Design • Document Architecture • …...

  25. Using Breakdown Structures • Project Leader decides on the architectural approach and level of detail of the WBS • Noun-type approach identifies items • call processor, detailed design • Verb-type approach identifies work • plan, document • Other approaches may utilize organizational or even geographic decompositions • marketing bid process, quality release criteria • department, software center • Well defined WBS is good for planning, reporting, etc.

  26. WBS Completion Criteria • WBS elements (tasks) are measurable • Start / End Events are clearly defined • Each “activity” has a deliverable • Time / cost can be estimated • Activity durations can be made within acceptable limits • Work assignments can be independent R. Wysoki, 1995

  27. Estimation • What gets estimated... • Some Problems encountered • Policies and Practices • Use of Historical Data • One method… Wide Band Delphi

  28. What Gets Estimated • Estimation may include: • Product Size (documents, Lines of Code, etc) • Effort Required (working day/week/month/year) • Schedule Required (e.g. resource/dependencies) • Resources Required and Available • Cost ($$ at management level) • Anything else that might be relevant.... • In other words: Estimate Everything… everything is an estimate (until the project is finished)!

  29. Estimation Problems (1) “Estimation is concerned with the prediction of uncertainties. It is more dignified than fortune telling, though not always more accurate....”

  30. Estimation Problems (2) • Example: a DoD contractor • Bid for contract (80 work years quote) • Contract awarded, planning started • Calculations showed 120 work years estimate • 50% budget overrun, $4,000,000 extra costs • DoD did not accept new quote (legal action!) • Super team of the best engineers was established to try to minimise the schedule overrun and loss • The project eventually took only 60 work years

  31. Estimation Problems (3) • Software estimates depend on: • the people who do the work (skills/experience) • the kind work performed (the product) • the information that is available (historical data) • The estimation paradox: • “Accurate estimates are generally required prior to getting the information needed to make the estimates”

  32. Estimation Problems (4) • Why is it hard to estimate software projects? • Requirements change • Platforms and tools/technologies change • Historical is data not available or not relevant • Don’t know project nature until after analysis • Some costs unrelated to code size (quality, usability, reliability, performance, management, etc) • Dependencies on customer/contractor/support

  33. Causes of Variation in Estimation • Variation in skill levels • of the estimator, of the development team members, etc. • Unexpected events (Murphy’s Law) • Efficiency of Work Time • how long is a day… interuptions, etc. • Mistakes and misunderstandings • happen to everyone all the time • We do not really know what factors will be operative when work is underway on a task… we narrow the variance by sufficiently defining the activity...

  34. A Center Estimation Policy • POLICY: • “a minimum of two (documented) estimation methods shall be used for any software project” • ….using more than one method to validate estimates is good practice… • POLICY: • “re-estimation shall take place at relevant points throughout the project lifecycle (as documented in the SPMP)” • ….the SPMP can document rules concerning when to re-estimate (and replan) …

  35. Example Estimation Practices • Provide “rough” estimates before a quote (Memorandum Of Understanding - MOU) • Start “formal estimation” after Project Kick-Off • Estimate the project in stages, e.g., • in Requirements Analysis estimate Design • in Design estimate Testing • Use historical data from previous/similar projects • Model and fast-prototype to obtain data • Use of expert opinion in Wide Band Delphi • Use of estimation tools (e.g., COCOMO)

  36. Historical Data for Estimation • Stored in a database, repository, folder, etc. • May come from... • previous project experience • personal process metrics • Examples: • Hours per page to create or review documents • LOC per week (productivity) • Number of problem reports per month or phase • % of working week spent on actual project work

  37. Methods of Estimating • By similarity…. Experience • With historical data • By expert advice • By Delphi • a group technique to extract knowledge • 3-point techniques (3 passes…) • collect and compare an optimistic, pessimistic and “most likely” estimate • Combine Delphi and 3-point with the Wide-Band Delphi technique

  38. Wide-Band Delphi Procedure • Distribute WBS to “experts” for preparation • Experts make their individual estimates for the average/min/max for each WBS item • Tabulate individual estimates average/min/max for each WBS item • Discuss assumptions/motivations for individual estimates until agreement is reached • Estimate the amount of work, not the schedule! (record schedule issues during the meeting)

  39. Guidelines for Estimation • Make sure the data is relevant • Obtain background (project profile) information • Make sure everybody uses the same units • Use lines of code, not assembler equivalent lines as size indicator • Know the accuracy of the estimate • Document all assumptions

  40. Key Project Documents: SPMP • Lifecycle Model & Process Tailoring • Organisational Boundaries and Interfaces • Project Responsibilities and Escalation Procedures • Management Objectives and Priorities • Defect Prevention Plan • Assumptions, Dependencies and Constraints • Risk Management • Staffing and Training Plan • Methods, Tools and Techniques • Work Packages and Dependencies • Resource Requirements and Allocation • Schedule

  41. Schedule • Determines which tasks • must be done sequentially • can be done in parallel • Applies the estimated time required for tasks • Usually represented graphically by • Gantt Chart • Pert Chart

  42. Scheduling The WBS...

  43. Scheduling - the Gantt Chart • The Gantt Chart is a bar chart • Length of bars are proportional to duration • Useful for understanding the set of tasks to be done at a specified time • Useful for tracking • Not good in showing task dependencies

  44. Scheduling - the Gantt Chart

  45. Scheduling - the PERT Chart • PERT Chart is a network diagram (like the CPM chart) • The PERT shows all tasks and their relationships (dependencies) • Useful in understanding when the set of tasks to be done can be completed • Useful in showing task dependencies • Not good for use in tracking

  46. Scheduling - the PERT

  47. Key Project Documents: SQAP • Project goals • Product goals • Project goals • Project goals setting • Should be measurable • Should be challenging, but not unattainable • Organizational goals • Project Metrics • To be collected by the project • Audits • Frequency

  48. Key Project Documents: SCMP • Defines the Organization and Responsibilities • Configuration Manager role • Team SCM Responsibilities • Configuration Control Board • Software Configuration Identification • Configuration Control Procedures • Auditing, Traceability and Accounting • Tool conventions and methods • Interface Control • Archiving Requirements • Reporting

  49. Key Project Documents: MBOOK Defines and contains: • Project metrics entries and summaries • Data for all defined quality metrics • Phase and end-of-phase data • Quality Gate results and milestone data • Change information • Estimation data MBOOK is updated regularly and at start and end of each phase

  50. Key Project Documents: Project Folder • The master document for all project activity • All team members must be aware of its contents • May be hardcopy, softcopy, or mixture of both • A softcopy folder may contain pointers to files • May be multiple folders • Contains project meeting minutes • May be web-based project folders • Significantly reduces hard copy • Much more convenient to use • Still may need physical folders to hold documents with “signatures”
